LIQUID-MIXER.

Specification of Letters Patent.

Patented Mari 10, 1914.

Application filed January 9, 1913. Serial No. 741,001.

To all 'UllOl/I it may rioll r-crn Be it known that I, JAMES J. \Vooo, a citizen of the United States, residing at Fort Wayne. county of Allen. 'State of Indiana, have invented certain new andfuseful Improvements in LiquithMixers, of which the followingis a specification.

My invention relates to liquid mixers, that is, apparatus adapted to violently ag tate theconten'ts of aliquid containing receptacle. and moreparticularly to the'beater or agitator for such apparatus.

My invention has for its'object a simple and improved agitating device which is capable of thoroughly mixing one liquid with another. To this end, I construct my agitator as adisk provided with one or more inclined holes therethrough, which are preferably inclined so that they tend to pump the contents of the liquid containing receptacle downward.

For a better understanding of my invention reference may be hadto the following description taken in connection with the accompanying drawing, in wlnch Figure 1 is a view of a llqllld mixer 1n connection with which an agitator embodying my invention may be used; Fig. 2 a plan view of m agita-tor,'and-F1g. 3 1s a sectional view 0 the agitator of'Fig.2 taken on the line 33.

In Fig. '1, I have illustrated my agitator in connection with the liquid mixer of my prior Patent No. 1,057,024, dated March 25, 1913. This mixer comprises an electric motor 1 which is mounted on a standard 2 and drives the'agitator 3 through a shaft 4. The

standard 2 is provided with lugs 5 and .6 which form bearings for shafts 7 and 8.

Arms 9 and 10, each having bifurcated ends. are secured at one end to the shafts 7 and 8 respectively, and the other bifurcated ends of these arms' are pivoted to a vertical arm 10 has a projection .13 extending beyond the rod 11 and adapted to act as a pawl in cooperation with a pivoted ratchet guard 15 is fastened to the adapted to cooperate in holding aliquid containing receptacle 16. Current supply wires 17 and 18 for the imotor l-enterthe standard near its bottom.

\Vhen the parts are in the position shown in full lines, the motor '1 is at rest and the *receptacle 16 is in its lowest position, from which it can be removed without spilling its contents. When it is desiredto agitate the contents of the receptacle, the parts are moved into the dotted position, which com pletes the circuit of the motor as fully described in my prior patent, and theagit'ator 3 is set in rapid motion thereby thoroughly mixing the contents of the receptacle.

The agitator 3 is shown in detail in Figs. 2 and 3 and consists of a disk having'one or more inclined holes 19 therethrough, ,the openings of the holes in the bottom of the disk trailing in the direction of rotation behind the openings-of the holes in the top of the disk. The disk preferably has fiat top and bottom surfaces to which the holes are inclined at an angle of substantially 45 degrees. If the holes are inclined as described above and shown in the drawing and the agitator rotated in the direction of the arrow. the liquid in the receptacle 16 will be set'in whirling motion and pumped downward or depressed. If one of the liquids to be mixed is viscous, as for instance eggs, it

is very difficult. to break it up into'smallparticles and mix it with-theother liquids in the receptacle. The sharpv edges of the holes 19 in my agitator, however, breakup such a viscous liquid in a very short-time, and the violence with which the liquids in the receptacle are pumped down thoroughly mixes them, without spattering. In thepar-i ticular construction of agitator shown, two holes 19 are provided,near the edge of the disk and except for these holes the agitator is smooth. I have found by experiment. that if my agitator is revolved at the speed usually employed in liquid mixers of the type shown in Fig. 1 and ina direction reverse to that of the arrow in Fig. 2 which will, pump the liquids upward, the agitation 'is so violent that the liquid will be thrown out of the receptacle.

Although I have illustrated my agitator in connection with the liquid mixer of'my prior Patent, No. 1,057,024, I desire it to be understood that it may be used with any type of liquid mixer in which the agitator is revolved.

What I claim as new and desire to secure by Letters Patent of the United States, is

1. The combination with a receptacle, of a shaft extending downward into said receptacle, means for rotating said shaft, and an 7 comprising a disk provided with an inclined.

' tator comprising a disk I therethrough near the edge of'said disk. the

agitator secured to said shaft. said agitator hole therethrough near the edge of said disk, the opening of the hole in the bottom of the disktrailingin the direction of retation behind the opening of the hole in the top of the disk.

2. The combination with a receptacle, of a shaft extending downward into said receptacle, means for rotating said shaft, and an agitator secured to said shaft, said agihaving substantially flat top and bottom surfaces and being pro- Yided with a plurality of inclined holes openings of the holes in the bottom of 'the disk trailing in the direction of rotation behind the openings of the holes in the top of the disk. Y

3.-The Combination with a receptacle, of l ashaft extending downward into said receptacle, means .for rotating said shaft, and 1 an agitator secured to said shaft, said agi tater comprising a disk having substantially flat top and bottom surfaces andbeing provided with a plurality of holes therethrough near the edge of said disk, said holes being inclined at an angle to said surfaces, the

openings of the holes in the bottom of the disk trailing in the direction of rotation behind the openings of the holes in the top of the disk whereby the liquid in said container is set in whirling motion and pumped downward.

4. The combination with a receptacle of a shaft extending downward into said receptacle. means for rotating said shaft, and an agitator secured to said shaft said agitator comprising a disk having substantially flat top and bottom surfaces with a plurality of holes therethrough near the edge of saidv disk, said holes being inclined sulistantially faces, the openings of the holes'in the bottom of the disk trailing in the direction of lo tation behind the openings of the holes in the top of the disk whereby the liquid in.

said container is set in whirling motion and pumped downward.
